Nitrogen abundance (by number) vs. ν_rot sin i. The colour scheme corresponds to the value of log g, and the evolutionary tracks are computed for initial masses of 30 M_⊙, 40 M_⊙ and 50 M_⊙ (red, brown, and orange solid lines respectively) for initial rotational velocities of 50, 110, 170, 220, 270 380 km s⁻¹ (Brott et al. 2011), which we multiplied by a factor of π/4 to take into account the inclination of the rotation axis (Hunter et al. 2008). The black dashed line represents the LMC baseline nitrogen abundance.
